Finder Mask for Argus 135mm Soligor

lacking a proper clip-on mask for the 4.5/135 Soligor in Argus Screw Mount, I improvised so I could do a film test on the lens.

 

Step 1: Using blue paint masking tape, I covered the 100mm mask on my Argus 35/100 Viewfinder, cutting out the portion over the hole.

 

Step 2: Then I placed another piece of masking tape over the finder, this time making it just a bit longer on one end, so I could fold it over to make a handling tab.

 

Step 3: I sandwiched a piece of electrical tape between the two pieces of masking tape, making sure to align the right and bottom edges.

 

Step 4: I cut out a portion of the electrical tape/second layer masking tape in the approximate dimensions of 0.165" x 0.105".

 

It was now ready to place on the finder. The left photo shows the mask in use, the middle photo shows it stored on top of the finder while using the 100mm mask, and the right photo shows the 100mm mask flipped up for using the 35mm finder, with the 135mm mask under the 100mm mask.

 

This is all just temporary until I can make a more precise mask with a better mounting system.
